基于本体相似的Web服务搜索

随着越来越多的Web服务被提交到UDDI注册中心注册，搜索一个合适的Web服务开始变得和在互联网上找到一个合适的页面同样困难。现有的技术主要是通过关键字匹配的技术来对UDDI注册中心Web服务的描述信息进行检索。但鉴于Web服务描述信息非常稀疏的特点，传统的信息检索技术并不能得到很好的效果，因此提出了基于本体的Web服务检索技术。在已有的对Web服务检索流程的改进的基础上，充分利用了从UDDI注册中心得到的Web服务描述信息，用本体来描述其内部的关系，并在此基础上应用本体相似技术来比较和匹配Web服务描述信息。

Ontology similarity search for Web services

Web Services provide a loose coupling way for the development of software and services. The software developers register their service in UDDI, on the other hand the customers of the service or the compound service developers search and find the specification of the service in UDDI. With the increase of Web service specification in UDDI, it is difficult to find out a suitable Web service in UDDI, just as finding a correct Web page in Internet. The existing technologies rely on the keyword match to search Web Services. For the sparse data in the specification of Web Service, the traditional information retrieval technologies are not applicable to resolve the issue. Therefore, a Web Services search and retrieval technology based on ontology was provided to make full use of the specification of Web Services in UDDI and find out correct Web Services. On the other side, ontology was used to describe the relations in the specification of Web Services and Ontology Similarity was used to compare and match Web Services.
